不同健康类型的马尾松林节肢动物多样性研究

摘要

Through the investigation on the arthropod in Masson pine stands with different health types, 816 individuals of arthropod were obtained, which belong to 2 classes, 13 orders, 63 families. Arthro-pods obtained in each stand were not the same in order, family, the number of in-dividuals, and the similarity coefficients of arthropod groups in different health types Masson pine were different. The order of different types of health Masson pine stands on the stability of arthropod community was health stand>sub-health stand>unhealthy stand. And the order of Arthropod species richness (S), the num-ber of species (N), diversity index (H'), evenness index (J) in different health types of Masson pine stands were health stands> sub-health stand> unhealthy stand, dominant concentration index (C) with the opposite situation .%通过对不同健康类型的马尾松林分中节肢动物种类的调查，采集到816号标本，分属于2纲、13目、63科。各林分中采集到的标本在目、科、个体数量上均不相同，不同健康林分之间节肢动物类群的相似系数大小不一。不同健康类型马尾松林分节肢动物群落在稳定性上的大小顺序为健康林分＞亚健康林分＞不健康林分。不同健康类型马尾松林分节肢动物物种丰富度S、物种数量 N、多样性指数(H′)、均匀度指数（J）的大小顺序均为健康林分＞亚健康林分＞不健康林分；优势集中性指数(C)的情况与之正好相反。
